Re: [Sipp-users] successfull calls for server performance
Well, so you just count the sent INVITEs (without retransmissions) and the received ACKs. You can get this information quite easily by using the -trace_shortmsg-function. n(ACK)/n(INVITE w/o retrans) is the successrate ;) br Michael On 2011-03-31 18:10, viswavardhanreddy karna wrote: Hi all, i want to measure depending on the success-rate relevant. i will measure server performance by sending number of calls/second to server to load the server and by that i will be measuring the no:of successful calls On Thu, Mar 31, 2011 at 4:00 PM, Michael Hirschbichler s...@hirschbichler.biz mailto:s...@hirschbichler.biz wrote: (Please do not forget to reply to the list too.)
